Can Orvego Fungicide be used by drench method to treat powdery mildew on dogwood trees?
Dogwood trees had powdery mildew last year. We want to treat by drench method.
Orvego Fungicide is not labeled to treat powdery mildew. Eagle 20EW is our most popular product for powdery mildew but it is not applied as a soil drench per the label. You would apply when conditions are favorable for disease development.
